IRB actually doesn't show the time by default, it shows what "self" is, along
with the line number and nested line number. Also, ir.exe's REPL does not set
the TOPLEVEL_BINDING constant, though running a file or a snippet with ir.exe
does:
$>ir.exe

Iirb is actually a library and has more features.
Iirb:
* can set the prompt in a .irbrc file
* can be nested (you can start a new irb session from within irb, even giving
it a new target object to use as self)
* as a library, irb can be incorporated into other projects
Irb is the REPL for MRI, it just happens that the current design of the DLR
gives a REPL pretty easily, so ir.exe is also a REPL.

When no arguments are passed, they both start a REPL console only that iirb
shows the time of each operation. Are there more differences?
Thanks,
Shay.
